This chapter introduces you to a new way to develop computer vision algorithms for the web. When a computer vision algorithm has to be written for the World Wide Web, normally it is a C++ program on the server that is executed when a client calls it via a web server, but with OpenCV.js, this way to develop computer vision algorithms is extended not only on the server but also extended to the browser client. The algorithms can be executed in the client browser, allowing developers to have more flexibility and use the benefits of running code in the clients' browsers.
In this chapter, we are going to learn the following:
- What OpenCV.js is and the benefits of client browser code
- Develop basic algorithms for image manipulation
- Work with video or webcam in the browser
- Manipulate frames with OpenCV.js
- Face detection in a web browser...
